According to Susan Slusser of the San Francisco Chronicle, Detwiler was granted his release after using the opt-out clause in his minor league contract. The southpaw had a rough 6.43 ERA through 14 relief appearances with Triple-A, though he was pitching much better recently. May 15 - 9:22 AM

Detwiler is back with the club that released him six days ago. He'll begin the year at Triple-A Nashville and try to work his way up to the big leagues. The left-hander has been with five teams over his last four seasons. Apr 1 - 7:46 PM

Detwiler exercised the opt-out clause in his contract after being told he wasn't going to make the Opening Day roster. The lefty holds an 11.88 ERA this spring and a 6.73 ERA in the majors the last two seasons. Mar 26 - 12:01 PM

Smyly underwent Tommy John reconstructive elbow surgery this past June and probably won't make his Cubs debut until somewhere around mid-to-late August in 2018, but this could prove to be a nice buy-low move for Chicago leading into the 2019 season. Smyly, 28, holds a 3.74 career ERA and 1.199 career WHIP in 156 major league appearances (85 starts). He also has an 8.7 career K/9.
